Hussain , 20 Jul 2015When I call the display becomes blank.. Presed the lock button bt didn't working plz help meAre you using flip cover or tempered glass. May be that is blocking the proximity sensor to work properly. You can remove it, but I can't force u to do this. .I think this is the only reason.

Honestly, I I have C4 for 5 days. After 100% fully charged the first 10-20% drains so fast. At the first 3 minutes it went 99% which is not normal. The only thing that annoying me. On the first time of 100% charged after I unplugged it went 99% suddenly! And then drained almost every minutes till 88%. While I,m typing it already drained 3%!
